Seems reasonable. But if you do change it incompatibly in future, then
allocate a new URL for the new version.

Of course complex numbers aren't themselves an extension (for ABIs that
are recent enough to cover C99, or that considered Fortran in the first
place), it's complex integers specifically that are a GCC extension.
(There might be other extensions beyond complex integers and VLAs in
structures that have ABI significance; those were just the obvious ones.)
